Title Smart Lighting as basic building block of Smart City: an energy performance comparative case study Type Journal Article
Year 2018 Publication Measurement Abbreviated Journal Measurement
Volume in press Issue Pages
Keywords (up) Energy
Abstract The aim of this work is to simulate and compare the energy savings potentially applicable to the consumption data of the Smart Street pilot system located at the ENEA Casaccia R.C. (Rome). The astronomical lighting system energy consumption (baseline) is compared to the simulation of a pre-defined regulation: it allows the lights dimming (and therefore a reduction of consumptions) based on a statistics averages of the traffic flow rate, differentiated according to the day of the week. Then the baseline consumption is compared to the simulation of an adaptive configuration based on the traffic flow rate.

Title Reducing the environmental footprint of church lighting: matching façade shape and lowering luminance with the EcoSky LED Type Journal Article
Year 2018 Publication International Journal of Sustainable Lighting Abbreviated Journal
Volume 20 Issue 1 Pages 1-10
Keywords (up) Energy; Lighting; Remote Sensing
Abstract The lighting of the Church of the Three Kings in Logatec, Slovenia was replaced in 2014. The power of the installation was reduced 96% from 1.6 kW to 58 W, and spill light from the site was effectively eliminated. As a result, the church is no longer visible in nighttime satellite images of the area, indicating a reduction of waste light from the site of at least a factor of 30. This article discusses the concept of sustainability with regards to cultural heritage lighting, within the context of this example.

Title Historical perspective on the physics of artificial lighting Type Journal Article
Year 2018 Publication Comptes Rendus Physique Abbreviated Journal Comptes Rendus Physique
Volume 19 Issue 3 Pages 89-112
Keywords (up) History; Lighting
Abstract We describe the evolution of lighting technologies used throughout the ages, and how the need for improvements was such that any new technology giving better and cheaper lighting was immediately implemented. Thus, every revolution in energy sources – gas, petrol electricity – was first put to large-scale use in lighting. We describe in some detail several “ancient” techniques of scientific interest, along with their physical limitations. Electroluminescence – the phenomenon by which LEDs directly convert electricity into light – was long thought to only be of use for indicators or flat panel displays supposed to replace the bulky cathode-ray tubes. The more recent uses of LEDs were mainly for street traffic lights, car indicators, small phone displays, followed by backlighting of TV screens. LED lamps for general lighting only emerged recently as the dominant application of LEDs thanks to dramatic decrease in cost, and continuous improvements of color quality and energy conversion efficiency.

Title Media Prophylaxis: Night Modes and the Politics of Preventing Harm Type Journal Article
Year 2018 Publication Information & Culture Abbreviated Journal Information & Culture
Volume 53 Issue 2 Pages 175-202
Keywords (up) History; Lighting; Society
Abstract This article develops the term “media prophylaxis” to analyze the ways technologies are applied to challenges of calibrating one’s body with its environment and as defenses against endemic, human-made harms. In recent years, self-illuminated screens (like those of computers, phones, and tablets) have been identified by scientists, journalists, and concerned individuals as particularly pernicious sources of sleep-disrupting light. By tracing the history of circadian research, the effects of light on sleep patterns, and the recent appearance of software like “f.lux,” Apple’s “Night Shift,” and “Twilight,” this article shows how media-prophylactic technologies can individualize responsibility for preventing harm while simultaneously surfacing otherwise ignored forms of chronic suffering.

Title Electric Lighting Policy in the Federal Government, 1880-2016 Type Journal Article
Year 2018 Publication Abbreviated Journal
Volume Issue Pages
Keywords (up) History; Policy; Lighting
Abstract Federal policies have targeted electric lighting since the 1880s with varying success. This dissertation examines the history of those policies to understand policy makers’ intent and how their decisions affected the course of events. This qualitative study poses three research questions: How have changes in lamp efficacy affected policy development? How and why have federal policies targeted electric lighting? How have private sector actors adapted public policy to further their own goals? The analysis uses an interdisciplinary approach taking advantage of overlapping methodologies drawn from policy and political sciences, economics, and the history of technology. The concepts of path dependency, context, and actor networks are especially important. Adoption of electric lighting spurred the construction of complex and capital intensive infrastructures now considered indispensable, and lighting always consumed a significant fraction of US electric power. Engineers and scientists created many lamps over the decades, in part to meet a growing demand for energy efficient products. Invention and diffusion of those lamps occurred amid changing standards and definitions of efficiency, shifting relations between network actors, and the development of path dependencies that constrained efforts to affect change. Federal actors typically used lighting policy to conserve resources, promote national security, or to symbolically emphasize the onset of a national crisis. The study shows that after an initial introductory phase, lighting-specific policies developed during two distinct periods. The earlier period consisted of intermittent, crisis-driven federal interventions of mixed success. The later period featured a sustained engagement between public and private sectors wherein incremental adjustments achieved policy goals. A time of transition occurred between the two main periods during which technical, economic, and political contexts changed, while several core social values remained constant. In both early and later periods, private sector actors used policy opportunities to further commercial goals, a practice that public sector actors in the later period used to promote policy acceptance. Recently enacted energy standards removing ordinary incandescent lamps in favor of high efficiency lamps mark the end of the later period. Apparent success means that policy makers should reconsider how they use lighting to achieve future goals.
